    Abstract: The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.

    Abstract: A method for encapsulating at least one data packet includes fitting at least one data packet into at least one column of an application data table of an array that also includes a coding data table having at least one column. Then, at least one remaining column of the application data table is filled with padding, and coding data is fit into at least one column of the coding data table of the array. At least one column of coding data is punctured based upon a comparison of a bit rate of incoming data packets and a threshold bit rate, with at least one column of coding data remaining after puncturing the column(s) of coding data. And after puncturing the column(s) of coding data, the data packet(s) in the column(s) of the application data table, and the at least one remaining column of coding data, are encapsulated.

    Abstract: An erasure information table includes one element for each column of a data frame, stored in an IP datagram buffer 66 and in an RS data buffer 67, instead of an element for each element of that column. Thus, CRC checking is performed against datagrams, instead of individual elements, of a received data frame, and effective error correction can be carried out by a Reed Solomon decoder 69. The effectiveness of the error correction is decreased since errors will be indicated as being present when actually an error is present in another row. The amount of memory needed to store the erasure information though is reduced. In another embodiment (Figures 9 and 10), a linked list includes an element for each series of datagrams which have the same error status (i.e. reliable or unreliable). Each element includes the start address of the first datagram in that sequence and indicates the error status. Different lists may be used for application data and for parity data.

    Abstract: Embodiments are directed to transmitting receiver-capacity-signalling data that specifies a plurality of receiver capacities to be used for receiving a service. The signalled receiver capacities may include: a type of time interleaver being used and a minimum burst interval between two consecutive bursts. The signalled receiver capacities may also specify: how often a physical layer pipe appears in frames, and/or a number of a frame in which a physical layer pipe appears for the first time during a super frame. Embodiments are directed to receiving the receiver-capacity-signalling data and if, based on the received receiver-capacity-signalling data, receiver capacity is sufficient for one or more selected services, performing service discovery and decoding the one or more services. Otherwise, decoding the one or more services may not be performed.

    Abstract: In accordance with at least one embodiment, fixed TDM slot/frame structure and statistical multiplexing are combined. A TDM slot, which is fixed (in size and position) is reserved for a variable bit rate service such that the bit rate of the TDM slot/channel is below the average rate of the service. Such a reserved TDM slot may be referred to as a service specific slot. Since the service specific slot is reserved with a bit rate below the average rate of the service, additional capacity is reserved from a rate matching slot, which may be common for multiple services. In this rate matching slot, the capacity may be shared between services according to any suitable strategy for allotting services to portions of the rate matching slot, including, but not limited to, a statistical multiplexing algorithm.

    Abstract translation: 根据至少一个实施例，组合固定TDM时隙/帧结构和统计复用。 固定（尺寸和位置）的TDM时隙被保留用于可变比特率服务，使得TDM时隙/信道的比特率低于服务的平均速率。 这样的保留TDM时隙可以被称为服务特定时隙。 由于服务特定时隙是以低于服务平均速率的比特率保留的，所以从速率匹配时隙预留附加容量，这对于多个服务可能是共同的。 在该速率匹配时隙中，可以根据用于将业务分配给速率匹配时隙的部分的任何合适的策略来在业务之间共享容量，包括但不限于统计复用算法。

    Abstract: Apparatus and methods are provided for adaptively determining a handover measurement interval. Power savings are achieved when a mobile terminal in a digital broadcast broadband network does not constantly attempt to measure the signal strength of nearby cells. By determining cell parameters, such as size and carrier frequency, and also determining dynamic information, such as signal strength and mobile speed over time, the time until the next handover measurement is adjusted up or down. When a mobile terminal is moving towards a transmitter in a cell, the handover measurement interval may be lengthened, and when a mobile terminal is moving away from a transmitter, the interval may be shortened.
